- A fast train bump into a slow train going the same direction, and they get coupled together. The fast train was initially going 6.93 meters per second and the slow train 3.1 meters per second. What is the final speed (in meters per second) once the two are coupled?A 2,000kg car is moving at 30m/s hits a 1,500kg car moving at 12m/s going in the same direction. The two cars stick together. How fast do the two cars move together immediately after the collision? Note that the roads were icy.A 2000kg jeepney moving at 45km/hr accidentally collides with a 1000kg parked car.

- You find yourself stuck in outerspace with nothing but your physics book and spacesuit. You have a mass of 108kg in your suit and your physics book has a mass of 3.7 kg. In order to make it back to your stationary spaceship before running out of air you must move at .29 m/s. How fast in m/s do you have to throw your physics book to achieve the speedA 500kg car moving to the north at 45m/s crashes head-on into a 600kg car that is moving the south at 23m/s.

- During a spacewalk, Dmitri finds himself floating 3 m from his space station's airlock. He only has one minute of air left. He has one detachable 10 kg toolkit, which he can toss to propel himself toward safety. How fast will he need to move to reach the airlock before he runs out of air?As you drive your car along a country road at night, a deer jumps out of the woods and stands in the middle of the road ahead of you. This occurs just as you are passing from a 55-mi/h zone to a 50-mi/h zone. At the 50-mi/h speed-limit sign, you slam on the car’s brakes, causing them to lock up, and skid to a stop inches from the startled deer. As you breathe a sigh of relief, you hear the sound of a police siren. The policeman proceeds to write you a ticket for driving 56 mi/h in 50-mi/h zone. Because of your preparation in physics, you are able to use the 25-m-long skid marks that your car left behind as evidence that you were not speeding. What evidence do you present? You must use work/energy methods to solve this problem!The coefficientsof friction between car tires and dry concrete are (s=1.0, k=0.80).A swimmer with a mass of 75 kg dives off a raft with a mass of 500 kg.
